Abstract
A container and contents monitoring system includes a device, a reader, a server, and a software backbone. The device communicates with the reader in order to determine the security of the container to which the device is attached. The reader transmits the information from the device to the server. The sensor senses a distance or an angle value between a door of the container and a frame of the container and the sensed value is then transmitted to the device. The device obtains a baseline value that is related to a calculated mean value. The device also obtains a detection threshold. The device determines if a security condition has occurred based on the sensed value and the detection threshold.
